Your Dr is right. Crack fracture
of knee should not be taken lightly. Knee joint is a load bearing joint. When we stand up & walk the entire weight is on the legs. And also as age advances, age related degenerative changes will occur in all bones & joints. Post menopausal women are more prone for osteoporosis
. So careless movements of knee now when it is compromised can result in residual damage & can result in recurrence later. So crepe bandage is not suitable now.
For crack fracture, knee should be immobilised for 6 weeks followed by physiotherapy
. Specific, muscle strenghening exercises should be done to restore the normal range of movements. Then load bearing exercises should be done. Squatting & knee bending should be avoided initially.
